Comparing constant acceleration in 1-dimension and rotational kinematics

In this simulation, you can compare the motion of a ball, which is influenced by gravity alone, to that of a disk, which has a constant angular acceleration directed counter-clockwise.

You can see the ball's motion diagram, with the position marked at 0.5 s intervals. You can also see the disk's motion diagram, with the position marked at 0.5 s intervals. You can then either see graphs of the ball's position, velocity, and acceleration, all as a function of time, or graphs of the disk's angular position, angular velocity, and angular acceleration, all as a function of time.
